Develop a vehicle and supply plan that supports extended deeper cave exploration.
This is an original reference for the first Subnautica. Your current depth rating, oxygen, available tools and navigation route determine when an objective is practical. Follow actual in-game PDA and Fabricator information for any values that vary by version.
How to use this information
Acquire Nickel later in deep regions and build a beaconed path through the cave system.
What to avoid
Do not enter a deep labyrinth with empty cells and no navigation plan.
